955905 Volvo.Penta Washer

START BY:a. remove timing gear cover The automatic timing advance is not used on the 943 loader. 1. Remove bolt (1) and the washer. 2. Install tooling (A), and loosen automatic timing advance (2) on the shaft. Remove tooling (A) and the automatic timing advance.Install Automatic Timing Advance
1. Install the bolt and washer in shaft (1) in the pump drive. Remove the plug from the pump drive housing, and install tool (A) in the plug hole. Turn shaft (1) until timing pin (A) engages in the notch in the shaft. Tool (A) will hold the fuel injection pump camshaft in the correct position to set the fuel injection timing of the engine. 2. Remove the bolt and washer from the shaft, and install automatic timing advance (2) on the shaft. 3. Be sure the threads on bolt (3) and the threads in the shaft of the pump drive are not damaged. Put clean oil on the threads.4. Install bolt (3) and the washer to hold the timing gear on the shaft. Tighten bolt (3) finger tight only. Bolt (3) must be tight enough to hold the gear clearance (backlash) out of the timing gears when the engine is turned. However, the timing gear must be able to turn on the shaft when the engine is turned to put the No. 1 piston on top center compression position (TDC). 5. Put No. 1 piston at the top center compression position (TDC) with the following procedure:a. Remove plug (4) from the flywheel housing. b. Turn the crankshaft clockwise (as seen from the front of the engine) until a 3/8"-16 NC bolt (5) at least two inches long can be installed through the timing hole in the flywheel housing and into the hole in the flywheel. Never turn the crankshaft backward to install the timing bolt in the flywheel. c. Remove breather (6) from the valve cover. Check to see if both rocker arms for the No. 1 piston can be moved backward and forward by hand. The No. 1 piston is at the top center compression position when the bolt is installed in the flywheel, and both rocker arms for No. 1 piston can be moved backward and forward. If both rocker arms cannot be moved, the No. 1 piston is not at the top center compression position. Remove the bolt from the flywheel. Turn the crankshaft clockwise (as seen from the front of the engine) one full turn (360°), and install the bolt again. 6. With the timing pin in the fuel injection pump housing and the timing bolt in the flywheel, tighten the bolt in the timing gear to a torque of 149 7 N m (110 5 lb.ft.).7. Check the timing as follows:a. Remove both the timing pin and timing bolt.b. Turn the crankshaft clockwise (as seen from the front of the engine) two full turns, and install the timing pin and bolt again.c. The timing is correct if both the timing pin and timing bolt can be installed at the same time. The timing procedure must be done again if the timing pin and timing bolt cannot be installed at the same time.d. Remove the timing pin and timing bolt when the timing is correct. 8. Install plug (4) in the flywheel housing. 9. Install breather (6) on the valve cover. 10. Install plug (7) in the fuel injection pump housing.Disassemble Automatic Timing Advance
START BY:a. remove automatic timing advance 1. Remove screws (1) and plate (2) from the hub. 2. Remove springs (3). Do not mix parts of weight assemblies (5).3. Remove limiters (4) and weight assemblies (5) from the hub. 4. Remove gear (6) from hub (7).Assemble Automatic Timing Advance
1. Put gear (1) in position on hub (2) as shown. 2. Put slides (3) in position on weights (4), and install the weights on the hub with the holes in slides (3) over the pins in the hub. Install limiters (5) as shown. 3. Install springs (6) in the openings between the weights and the limiters. 4. Put plate (7) in position, and install the screws that hold it in place.END BY:a. install automatic timing advance
